CONTACT Belleville Springs® combine two important features for improved bolt connections. Their conical shape provides a reactive force and a high elasticity of spring return to compensate for developed looseness, loss of bolt tension due to applied surface deterioration, or movement due to thermal expansion and contraction. The hardened, serrated profile "grips" the lower surface of the bolt or nut to prevent the loss of tension that normally occurs during extreme vibration or severe shock.

CONTACT Bellevilles® come in size that correspond to a wide range of screw head sizes, including hex head socket screws. They can also be used in Sems® assemblies. Made of selected high quality carbon spring steel, these springs are available with mechanical zinc, cadmium or tin plate, stainless on request.
